 * :code:`regularisation_iterations` defines how many inner iterations for regularisation performed on every step of the outer (FISTA) algorithm. This can depend on :code:`regularisation_type` and  :code:`subsets_number`. The general rule is when :code:`subsets_number` is smaller then :code:`regularisation_iterations` should be increased.
